Please find below a communication from the EXAMINER in charge of your application, S. No. 371,817, filed May 4, 1907, Apparatus for Transmitting Electrical Energy through the Natural Media. Bulsors. Commissioner of Patents. This action is in response to amendment filed May 23, 1906. The source G in Figure 5 should be illustrated as an alternator or condenser, as stated on latter part of page 6. The reference character D' is employed to designate the terminal, as stated in line 9 of page 7, and also indicates the drum of insulating material, as stated in line 15 of page 8. Correction of the specification and also of the drawing should be made correspondingly. The insula ting drum should be shown according to the draftsman's chart. The feature of providing the hocd a with slots should be illustrated; attention is called to line 13 of page 8. Claims 9, 10, 11, 12 and 15 to 27 are again objected to for the reason that the feature specified in said claims, to wit, "plurality of x X X x surfaces, each having a relatively large radius of curvature" is not descriptive of applicant's device. The description of the metal plates Las on page 5, line 3 from bottom, shows that said spherical plates are of small radius of curvature. claims 7, 8, 10, 11 12, 37, 39, 40, 43 and 44 are objected to in that the same include alternative expressions. Attention is called to ex parte Phillips, 135 0. C., page 1801. 37147 743
